STEAM-BOILER FOR GAS-GENERATORS.

SPECIFICATION forming part of Letters Patent No. 273,522, dated March 6,1883.

Application filed December .22, 1882. (N0 model.)

To all whom it may concern Be it known that we, JOHN HANLON, of the cityand State of New York, JAMEs E. LEAD- LEY, of Camden, New Jersey, andSILAs GIBBS, of Warren county, New Jersey, have invented a new anduseful Improvement in Steam-Boilers for Gas-Generators, of which thefollowing is a clear, full, and exact description, reference being hadto the accompanying drawing, in which the figure is a section of avertical steam-boiler with our improvements attached. A

Our invention has reference more particularly to a vertical steam-boileradapted to be used in the manufacture of gas, and which receives itsheat from the generator, as set forth in our application for a patent ona gas apparatus filed of even date herewith, reference being madetherein to this application; and it consists in the peculiarconstruction of the boiler, as hereinafter explained and claimed.

To enable others skilled in the art to make and use our invention, wewill proceed to describe the exact manner in which we have carried itout. w

In the drawing, A represents a vertical steam-boiler provided with thelines B, extending from the chamber 0 up into the upper part, 1),, ofthe boiler. From'this upper portion, D, we provide a central flue, E,extending entirely through the boiler and passing below the water-sealF, as shown. The top of the boiler is provided with a "alve or cap, J,which can be readily raised or lowered at pleasure. The waste heat andgases from the gas-generator while the blast is applied, and passing upthrough the flues B heat up the boiler, and

finally escape through the top of the boiler,

the cap being raisedto permit such escape. When the blast is shut offfrom the apparatus and the generation of the gas begins, the hot gasesenter the boiler and pass through the flues B to the upper portion, D,whence they escape downward through the central flue, E, thuscompensating, by heating up the central flue, for the loss of the heatresulting from shutting off the blast. By this means we are enabled tokeep one boiler under a comparatively regular heat during the periodicalchanges in the apparatus, consequent upon well-known manner ofmanufacturing gas;

The central tube, E, passes entirely below the boiler into a water-sealwithin the chamber H, in which the gas enters and from which it passesto proper receptacles prepared for the purpose.

We are aware that it is not broadly new to heat a boiler by the wasteheat from a, gasgenerator, nor do we claim such as our invention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The vertical boiler A, provided with an adjustable cap, J, and the tinesB, and central
